Thanks man you were a massive help in the Mark X hunt and true most Mark Xs that are for sale currently has a very shady past, and I found a good quality car and the owner asked me 55 million? (still worthy when comparing to a premio) but I couldn't make up my mind of spending that much for a car which is in anyway 12 years older to the date.
Well frankly my father will use this car mostly after 2021 because I'm going abroad to finish my degree, so I need to make the most quietest, most comfy teana in the island. So I don't mind sacrificing driving dynamics because he only drives this car 4km daily through suburban traffic. So my plan is to upgrade the suspension (air ride the car if possible), soundproof the whole car etc. So anything ideas/tips regarding that mission is highly valuable.
For the time being I'm thinking of getting a proper exhaust system with valves and increasing the sweet induction sound of the NA V6. I have some experience around VQs since I did a megasquirt build for one of my friends VQ30 engines in a Gloria Y33. But I'm keeping this as a second priority for now because firstly I need to make the car as comfy as it can be, so later if I have some time and money to kill I can enjoy a proper exhaust note.
